|---|---|---|---|
| 1 | Description | Yellowish, highly refrective liquid, becoming darker with age and on exposure to light. A saturated solution of it is neitral to litmus. | Colourless or yellowish to brownish-yellow or pinkish, highly refrective liquid, becoming darker with age and on exposure to light. A saturated solution of it is neutral or slightly acid to litmus. |
| 2 | Solubility | Complies | Sparingly soluble in water, usually forming a cloudy solution; dissolves in solutions of fixed alkali hydroxides. Miscible with alcohol, with ether with glycerin, with ethanol (96%) and with methylene chloride |
| 3 | Identification A (By IR) | Complies | IR spectra of the sample should be concomitant with IR spectra of the corresponding standard |
| 4 | Identification B (By GC Chromatogram) | Complies | The retention time of the major peak of the sample solution corresponds to that of the standard solution, as obtained in the assay. |
